Actor Christian Bale is set to become a father for a second time.

Former model Sandra 'Sibi' Bale, 43, displayed a fuller figure as she accompanied The Dark Knight star to the Oscars in Hollywood last Sunday (02Mar14), and now it's been revealed she is pregnant with a sibling for their daughter Emmeline, who turns nine later this month (Mar14).

A representative for the 40-year-old Brit has declined to comment.

The couple wed in 2000.
